How to find distance of object on incline plane by ignoring resistive forces?

A 1200-kg car is being towed up an 18o incline by means of a rope attached to a truck. The rope makes an angle of 27o with the incline. What is the greatest distance that the car can be towed in the first 7.5s starting from rest if the rope has a breaking strength of 4.6 kN? Ignore all resistive forces on the car.How to find distance of object on incline plane by ignoring resistive forces?
summation forces in x direction





4600cos9 - mgsin18 = ma





solve for a





x = vt + 0.5at^2


x = 0.5at^2
